Phal gigantea culture - how difficult is it?

[brammn]

Traditionally I've kept Catt's and Laelias with the odd Vanda and bulbophyllum but I've decided to be adventurous and branch out and try something different so I'm looking at a few Phal species (well - I have a few already and they're doing ok).

I've got the option to buy a gigantea 'alba' (catch is its not cheap). I've read mixed reviews online - what are people's experiences, how difficult are they? I'm keen to understand before I invest.

I live in the UK, so winters are fairly cool and not a lot of light in winter which is my main concern. Certain more fragile plants come in the house over winter (that being said I am seriously considering a giant propagator and moving the fragile plants into the garage with LED grow lights over them to maintain 12 hours light a day and temps over winter this year...)
